2018-06-05util/sconfig: Get rid of struct headerFurquan Shaikh
Now that chips and devices are treated differently in sconfig, this change gets rid of struct header and add_header function which were responsible for maintaining list of headers that need to be added to static.c. Instead, struct chip is re-factored into struct chip and struct chip_instance, where chip is a list of unique chips required by the mainboard whereas chip_instance is an instance of the chip. One chip can have multiple instances dependending upon the devices in the system. Also, struct device is updated to hold a pointer to chip instance instead of the chip structure. This unique list of chips is then used to add appropriate headers to static.c BUG=b:80081934 TEST=Verified using abuild that all boards compile successfully.

2018-06-05util/sconfig: Get rid of bus pointer in device structureFurquan Shaikh
The only reason bus pointer existed in device structure in sconfig was to allow a node to point to the parent which could be a chip and bus which is the true parent in device tree hierarchy. Now that chip is no longer a device, there is no need for separate bus and parent pointers. This change gets rid of the redundant bus pointer in struct device in sconfig. BUG=b:80081934 TEST=Verified that static.c generated for all boards built by abuild is same with and without this change.

2018-06-05util/sconfig: Re-factor sconfig to not assume chip as deviceFurquan Shaikh
This change adds a new structure "struct chip" to identify elements of type chip rather than re-using the structure for device. Until now chip was treated as a device while generating the parse tree and then device tree postprocessing skipped over all the chip entries in children and sibling pointers of device nodes. With this change, the device tree will only contain struct device in the parsed tree. It helps by avoiding unnecessary pointers to chip structure as children or next_sibling and then skipping those elements in post processing. Every device can then hold a pointer to its chip. When generating static.c, chip structure is emitted before device structure to ensure that the device structure has chip within its scope. Externally, the only visible change in static.c should be the order in which chip/device elements are emitted i.e. previously all chips under a particular device were emitted to static.c and then the devices using those chips. Now, all chips are emitted before all the devices in static.c BUG=b:80081934 TEST=Verified that abuild is successful for all boards. Also, verified that static.c generated for eve, kahlee, scarlet, asrock imb_a180 is unchanged from before in node definitions.

2018-05-11devicetree: Add USB device typeDuncan Laurie
This commit adds support for describing USB ports in devicetree.cb. It allows a USB port location to be described in the tree with configuration information, and ACPI code to be generated that provides this information to the OS. A new scan_usb_bus() is added that will scan bridges for devices so a tree of ports and hubs can be created. The device address is computed with a 'port type' and a 'port id' which is flexible for SOC to handle depending on their specific USB setup and allows USB2 and USB3 ports to be described separately. For example a board may have devices on two ports, one with a USB2 device and one with a USB3 device, both of which are connected to an xHCI controller with a root hub: xHCI | RootHub | | USB2[0] USB3[2] device pci 14.0 on chip drivers/usb/acpi register "name" = ""Root Hub"" device usb 0.0 on chip drivers/usb/acpi register "name" = ""USB 2.0 Port 0"" device usb 2.0 on end end chip drivers/usb/acpi register "name" = ""USB 3.0 Port 2"" device usb 3.2 on end end end end end Change-Id: I64e6eba503cdab49be393465b535e139a8c90ef4 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/26169 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

2016-05-16sconfig: Add a new generic device typeDuncan Laurie
Add support for a basic generic device in the devicetree to bind to a device that does not have a specific bus, but may need to be described in tables for the operating system. For instance some chips may have various GPIO connections that need described but do not fall under any other device. In order to support this export the basic 'scan_static_bus()' that can be used in a device_operations->scan_bus() method to scan for the generic devices. It has been possible to get a semi-generic device by using a fake PNP device, but that isn't really appropriate for many devices. Also Re-generate the shipped files for sconfig. Use flex 2.6.0 to avoid everything being rewritten. Clean up the local paths that leak into the generated configs.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

2012-07-13MPTAPLE: generate from devicetree.cbSven Schnelle
This patch adds support for autogenerating the MPTABLE from devicetree.cb. This is done by a write_smp_table() declared weak in mpspec.c. If the mainboard doesn't provide it's own function, this generic implementation is called. Syntax in devicetree.cb: ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN> The ioapic_irq directive can be used in pci and pci_domain devices. If there's no directive, the autogen code traverses the tree back to the pci_domain and stops at the first device which such a directive, and use that information to generate the entry according to PCI IRQ routing rules.
